✦ Synopsis

Water infiltration in porous materials is investigated in this study. A highly nonlinear hydraulic dtflusivity function is considered in the physical model. The orthogonal collocation method is employedfor solving the governing nonlinear d@erential equation. The present numerical solutions for porous materials are in good agreement with the experimental data of Gummerson et al. Because of its high accuracy, computational stability and easy application, the orthogonal collocation provides a good alternative for tackling the nonlinear water infiltration problem.
